Django CKEditor 上传图片提示“不正确的服务器响应”的解决办法

#Django CKEditor 上传图片提示“不正确的服务器响应”的解决办法| 来源: 网络整理| 查看: 265

开发环境

django 1.11

django-ckeditor 5.3.1（CKEditor 4.7.3）

发生背景

前端页面引用了 CKEditor 富文本编辑器，Django 未登录的时候上传文件就会报："不正确的服务器响应"。

错误提示

Incorrect Server Response

控制台日志

GET /admin/login/?next=/ckeditor/upload/ HTTP/1.1

从控制台可以看出来，会跳转到 admin 登录页面，也就是需要验证登录才能上传，那怎么才能取消登录验证呢？

查看 ckeditor 源码

..\Lib\site-packages\ckeditor_uploader\urls.py

from __future__ import absolute_import import django from django.conf.urls import url from django.contrib.admin.views.decorators import staff_member_required from django.views.decorators.cache import never_cache from . import views if django.VERSION >= (1, 8): urlpatterns = [ url(r'^upload/', staff_member_required(views.upload), name='ckeditor_upload'), # url(r'^upload/', views.upload, name='ckeditor_upload'), # ckeditor 上传文件不验证登录状态 url(r'^browse/', never_cache(staff_member_required(views.browse)), name='ckeditor_browse'), ] else: from django.conf.urls import patterns urlpatterns = patterns( '', url(r'^upload/', staff_member_required(views.upload), name='ckeditor_upload'), url(r'^browse/', never_cache(staff_member_required(views.browse)), name='ckeditor_browse'), )

在上面第 12 行代码这里可以看到，views.upload 还加一个 staff_member_required 验证，点进去看一下：

..\Lib\site-packages\django\contrib\admin\views\decorators.py

from django.contrib.auth import REDIRECT_FIELD_NAME from django.contrib.auth.decorators import user_passes_test def staff_member_required(view_func=None, redirect_field_name=REDIRECT_FIELD_NAME, login_url='admin:login'): """ Decorator for views that checks that the user is logged in and is a staff member, redirecting to the login page if necessary. """ actual_decorator = user_passes_test( lambda u: u.is_active and u.is_staff, login_url=login_url, redirect_field_name=redirect_field_name ) if view_func: return actual_decorator(view_func) return actual_decorator

从 staff_member_required 可以看出验证了 lambda u: u.is_active and u.is_staff 状态，所以我们要想去掉 ckeditor 的上传文件的验证，就需要放开登录验证，通过修改 ckeditor 上传路由的那行代码，能关掉登录验证。

解决方法

..\Lib\site-packages\ckeditor_uploader\urls.py 下把 staff_member_required 去掉：

from django.contrib.admin.views.decorators import staff_member_required urlpatterns = [ # url(r'^upload/', staff_member_required(views.upload), name='ckeditor_upload'), url(r'^upload/', views.upload, name='ckeditor_upload'), # ckeditor 上传文件不验证登录状态 url(r'^browse/', never_cache(staff_member_required(views.browse)), name='ckeditor_browse'), ]

也可以自己写一个验证规则，替换掉 staff_member_required。

staff_member_required 拓展

此函数可以拓展到任何一个路由上，做登录验证，也可以重写 staff_member_required 验证逻辑。

比如，本地的 media 文件需要登录了才能查看

# django 1.11.x

from django.conf.urls import url from django.views.static import serve from django.conf import settings from django.contrib.admin.views.decorators import staff_member_required from django.contrib.auth.decorators import login_required urlpatterns = [ url(r'^media/(?P.*)$', staff_member_required(serve), {"document_root": settings.MEDIA_ROOT}), ]

# ..\Lib\site-packages\django\contrib\auth\decorators.py

def login_required(function=None, redirect_field_name=REDIRECT_FIELD_NAME, login_url=None): """ Decorator for views that checks that the user is logged in, redirecting to the log-in page if necessary. """ actual_decorator = user_passes_test( lambda u: u.is_authenticated, login_url=login_url, redirect_field_name=redirect_field_name ) if function: return actual_decorator(function) return actual_decorator
